摘　　要：对"Siberia"百合种球在30～45℃水中进行热处理120 min,研究种球的冷藏效果及冷藏过程中的生理变化,并与未经热处理的种球对照,结果表明:40℃热处理能有效抑制冷藏过程中前期的呼吸强度;同时对POD、CAT活性产生了影响;降低了冷藏前期淀粉酶活性,延缓淀粉的降解速率,有效清除MDA累积,降低细胞膜透性,种球的冷藏品质得到改善;40℃热处理120 min可作为种球冷藏前的预处理技术加以应用。The ＇Siberia＇ lily bulbs were heat-treated for 120 minutes in 30-45 ℃ water to study the cold storage effect and the physiological change during the cold storage process compared with the control of bulbs without heat-treating.The results showed that the 40 ℃ heat-treatment could effectively inhibit the respiratory intensity in the early-middle period of the cold storage process;it also affected the activity of POD,SOD and CAT;it reduced the amylase activity in the early period of the old storage process;it delayed the degradation rate of starch and effectively eliminated the accumulation of MDA and also delayed the cell membrane permeability,the cold storage quality of bulbs was improved.The method of 40 ℃ heat-treatment for 120 minutes can be applied as a pretreatment technology before cold storageof bulbs.
